Boptima,

You have to be careful here because if you configure the code wrong, the data generated will be unreliable. How you configure this will depend on how you want to look at the data. For instance if you just put the same tracking code on the sub-domain, all data will be aggregated into the same profile. If you create a new profile, you will have separate data however if your site is set up to have visitors perform actions on the subdomain after leaving the main domain (i.e. a shopping cart), then your data will be misleading if you don’t enable cross domain tracking.

Here is a pretty good guide on how to set things up,
